Nature of Form is a book for design exploration. It's a book about nature, its forms and the nature of those forms.
Although inspiration knows no concept of time, place or context, we can certainly increase our exposure to stimulate our artistic side. While you can always take a stroll, or spend hours on the internet it would conclude a more unproductive bustle than a consequential one. Hence, the book, Nature of Form, which constitutes abstractions of natural elements into Forms, Textures and Colors.
In design we have such a process to derive aesthetics, called 'form development'. It involves having to take inspirations from around and derive lines and curves from it. It's all good but years and years of same practice as lead to taming of many inspirations, especially form nature.
It simply makes your process of inspiration hunt easier. It's an ocean of inspiration. It's limitless possibilities in your hand, at your disposal.
